After running this against a single vhdx file, the disk remained mounted at the end of the procedure.

Interestingly, if I run this against a folder I don't have the issue.

Any thoughts on how to resolve this??

I have tested this and it seems that the disk does not always dismount in the proper way. I will check this out, thanks for the comment mate

Hello, we have changed line 434 of the Resize-UserProfileDisk to $mountedupd = Get-Volume | Where-Object {($.filesystemlabel -like 'Profile*') -or ($.filesystemlabel -like 'O365*')} because we found out that the line 434 is looking for a disk called "User Disk" that did not exists. This resolved the issue of not unmounting the VHDX drives.
